Can Yorkies Have White Hair?

Yorkshire Terriers are known for their distinctive blue and tan coats. However, some Yorkies may have white hair in their coats. This can be caused by a number of factors, including genetics, age, and diet.

Genetics

The genetics of a Yorkie play a major role in determining its coat color. The Yorkie’s coat is made up of two types of hair: guard hairs and undercoat. The guard hairs are longer and coarser, while the undercoat is shorter and softer. The color of a Yorkie’s coat is determined by the pigments in these hairs.

Yorkies have two genes that determine their coat color: the A gene and the B gene. The A gene controls the production of black pigment, while the B gene controls the production of brown pigment. A Yorkie that has two copies of the A gene and one copy of the B gene will have a black coat. A Yorkie that has two copies of the B gene and one copy of the A gene will have a brown coat. A Yorkie that has one copy of the A gene and one copy of the B gene will have a blue and tan coat.

White hair in a Yorkie’s coat can be caused by a number of different genetic mutations. One of the most common mutations is a mutation in the A gene. This mutation can cause the gene to stop producing black pigment, which results in white hair.

Age

As Yorkies age, their coats may begin to turn white. This is because as a Yorkie ages, its hair follicles begin to produce less pigment. This can result in the hair becoming lighter in color or even turning white.

Diet

The diet of a Yorkie can also affect the color of its coat. Yorkies that eat a diet that is high in protein and low in carbohydrates are more likely to have a dark coat. Yorkies that eat a diet that is high in carbohydrates and low in protein are more likely to have a light coat.

Conclusion

White hair in a Yorkie’s coat can be caused by a number of factors, including genetics, age, and diet. If you are concerned about the color of your Yorkie’s coat, you should talk to your veterinarian.
